2 Claims.

This invention relates todevices'for supporting,

driving andpresenting views, images, advertisements and even articles, and morei'particularly concerns projection or presentation'iapparatus 6 the supportsof which, usually inthe. shapedf plates or frames receivingthe images or advertisementslto be projected or presented, are'mount- "ed onsuitable bands. 1

The projection or presentation apparatusin #10 question devised up to now were usually some- "what cumbersome, and this particularly owing to thecumbersomeness of the 'bands'carrying the plates; or" frames I and of the systems .driving arid presenting. the said .plates or frames, which sys- "tems werefmoreo'ver complicated =and; =iconsequently, of airelative'ly "high cost price.

The inventio'n'hasffor object to provideappa- --ratus of the type, in questionwhich are compact, very rsimplepand of a low costprice comparae tively 'tor-existing:apparatus owing to the fact that'the: supporting, drivingandvpresentationede- :vicesthey comprise are themselves according to the invention aoffireducedcumbersomeness--:a;nd

In providing for instance an advertising apparatus projecting images and advertisements, and comprising a succession of plates carrying the images and advertisements to be projected, the said apparatus is constructed in the usual manner as far as the frame and projection apparatusproper are concerned, but, concerning the devices, according to the invention, for supporting, driving and presenting the plates, it is constructed in the following manner or in an approximately similar manner:

The band carrying the plates 1 is an endless band composed of links 2 assembled and'joined together by means of pivot spindles. To each link 2 is secured, by any suitable means, a plate support constituted by two slides 4 in which is fitted the plate to be carried by the link along two of its edges, the said plate being held, once in position, by two bent parts 5 and 6. The plate support of each link is secured on the link, so that the plate carried by the support is perpendicular to the link and parallel to the two axes of the latter.

The said band carrying the plates is supported and driven by a shaft 7 having a square cross section.

A kind of Maltese cross 8 is mounted on the shaft 7 so as to rotate with the same, this Maltese cross being alternately driven by a plate 9 carrying a claw 10, to which plate 9 is secured an abutting segment 11, in the usual manner. 4

The said Maltese cross 8 is rigidly secured on the shaft 7 in such a manner that when this Maltese cross 8 is at rest, the plate 9 still rotating in a continuous manner, the shaft I having a square cross section has one of its faces hori zontal.

The plate 9 is actuated by'a suitable motor,

in the known manner, and through suitable transmissions.

From the foregoing and from the accompanying drawing. (Fig-3), it' will easily be understood-that a projection apparatus provided with the devices for supporting, driving and presenting plates carrying images or advertisements and constructed according to the invention, is of very reduced cumbersomeness and very simple. In fact, the plates carried by the endless band are -so to-speak piled upaccording to two vertical stacks, the distance separating them being function of the side of the square supporting and driving shaft and, consequently, is relatively small, and a chain of small length can carry a large number of plates. Moreover, owing to the fact that the shaft '7 'has a square cross section, and is rigid, as indicated, with the Maltese cross 8,'at the same time as it supports and drives the veniently constructed so as to be easily removed and replaced in position, for instance by forming these sp ndles in'such' a manner thatv one of I their journals (journal 12) is longer than the other'and that these spindles, or at 'leastrtheir shorter journal, are so-mounted as to havesufiicient play in their bearings to be easily removed,

.a suitable spring 13 being used for holding them a in position. It is then very easy to do away with manufactured by cutting out and bending operations, as shown in Fig. 4 of the drawing. The

plate 1 carried by each support is then held in position by a bent portion 14 and two small suitable springs 15 which constantly press the plate against the support, the slides being omitted.

It will be understood that the invention is not limited in any way to the mode of application and. to the forms of construction which have been more particularly indicated, as it includes on the contrary all modifications of the same.

What Iclaim as my invention and desire to secure by Letters Patent is:

1. A device of the character described including a rotatable shaft the main portion of which -is square in cross section, a Maltese cross fixed directly to the squared portion of the shaft, means cooperating with the Maltese cross for effecting intermittent rotation of said shaft, the squared portion of the shaft and the Maltese cross being so fixed relatively to each other that during each of the intermittent stoppages the upper faceof the squared portion of the shaft is in ahorizontal position, a chain operating about the squared portion of the shaft, plate supports carried by said chain, and said chain including a a plurality of links each of which carries a plate support and has a length substantially corresponding to the width of the squared portion of said shaft so that when each link reaches the top it is supported on the upper face of the squared portion of the shaft and maintains the plate support perpendicular to said upper face.

2. In a device of the character described, an endless band in the form of a chain composed of a plurality of plate supporting links and pintles connecting the links together, each pintle having a short journalling portion and an elongated journalling portion, and a coil spring arranged about the elongated journalling portion for yieldingly and releasably holding the short journalling portion into position.
